Citrus Salt

I used Maldon sea salt flakes here, but you can certainly experiment with other kinds of salt (this looks beautiful). Also, try to buy good, organic, citrus. And avoid waxed citrus. If that's what you have on hand though, just be just to give it a good scrub with warm water. Also, dry completely before zesting.

For each type of salt you'll need:

1/2 cup / 2.25 oz / 65 g flaky sea salt
1 tablespoon citrus zest

Preheat your oven to oven 225F / 105C. Combine the salt and citrus in a medium bowl and mix well. Really work the zest into the salt, making sure there aren't any clumps of zest. Spread across a parchment lined baking sheet. If you're making more than one flavor of salt, repeat this as many times as necessary. For example, this time I made 6 salts, and I arranged them across two baking sheets (see photos).

Bake for 70 minutes, or until the citrus is completely dried out. Flecks of zest should crumble when pinched between your fingers. Remove from oven and allow to cool a bit. At this point you can pulse each salt a few times in a food processor if you like, which is what I do. Or, you can enjoy it as is. Salts keep in an air-tight jar for a couple of months.
